Dear Frenchy, or should I call you Pilou?

First and fore most I want to thank you for your patience. This must be trivial to experts like you and Michael.

The reason that I am taking so much time and care with this, is that aligning these figures is extremely important for me to get an accurate representation of the configuration. Once I have a Moi description for the configuration an iges file is exported to a grid generation program to produce a computational fluid dynamics simulation of the configuration.

I am attaching a moi file with the three images inserted into rectangles as you suggested. The images have been clipped as close as possible and I am attaching them also. The rectangles measure 96'5" (96.41667') long by 93'6" (93.5') wide, by 25'10" (25.83333') high. I am attaching a file called g5503_view which shows the original dimensions of the 3 views.

The problem that I have is that if you draw a line from the leading edge of the engine inlet in the top view, it does not line up with the engine in the side view. This misalignment would be critical.

Is there something that I am doing wrong or is this something that you see in your own work? Any help you can provide would be greatly appreciated.

Sincerely,
Bill

<< Dear Frenchy, or should I call you Pilou?

Pilou is more friendly! Frenchy is more general! ;)

When I say images is not inside your file, it's that you can save the 3 images directly with your 3Dm File!

Case: View / Properties / Embed Image Data in 3DM File
So I will can see what that you do exactly! ;) (Images, position, scale...)

Of course file will be a little more big but...

If something is not well aligned :
either original scale of one image is not at the good scale
or trim is somewhere bad
or aligment is not well realised
or...

Courage! :)

Ps I am not very fluent with imperial measures - an headache nightmare! :)
Decimal is a dream in comparaison! :D

In any case dimension are not important if you have 3 images well fited between them!
You will can resize the 3D model at the end if you need some 2D / 3D drawings for Print or...! ;)

Dear Pilou,

I have modified the properties of the images as you suggest. I am learning something new. Does this version of the file include the images?

Sincerely,
Bill

<< Does this version of the file include the images?
Of course yes! We are in 2015! ;)

And yes there is a little problem with the side views! In height and weight ...for the reactor (?) and also for the top of the cabin!!!
So you must adapt it! Maybe original image was deformed on the 2D prog ...

Hi Bill,

Probably the images are not accurate - if the images are just kind of quick sketches that have differences between them then there won't be any way to align them 100%.

They need to be accurate views of the same exact object if you want them to align properly.

Thank you very much for helping me understand better the process of aligning images. I agree with you that this particular 3view is nou accurate enough and I will look for a better one

Sincerely
Bill

Hi Bill,
is that a Gulfstream G500/G550? Otherwise I converted( to PDF via Photoline) and imported the SVG-file from this Wikipedia article https://en.wikipedia.org/wiki/Gulfstream_G550#Specifications. These are actually all unconnected curves, no tracing necessary. I grouped the curves and named them after their initial view, so front, side and top. Might be of some help, i dunno.



Best,
Marco

Marco,

Thank you very much for your input. I found it very interesting. I am not sure that I no what an SVG file, or how you obtained it, but your geometry matches much better than the 3 view that I had.

Thank you again for you help and guidance.
